Meta Pixel does not activate

I have had the issue with 2 of my accounts so far

I have tried to setup the Meta pixel as both custom code and Meta Pixel with a trigger all page view.
However, they are not detected by Meta.

Using the Meta Pixel Helper, I get this error message :
Pixel Helper found your Meta Pixel, but the pixel has not been activated for this event and no information has been sent to Meta. This may be due to an error in the code or if the pixel fires on a dynamic event, such as a button click.

My debug on Piwik does confirm both my tags do activate.

How to fix the issue ?

Hello @JulieS_Duq

Is it simple page view pixel or custom event?

Hello @jfidala

I’ve tried both and none worked

@JulieS_Duq can you provide more details about this website? I can take a look and check what might be the issue

@jfidala it would be https://pairtopair.lu

@JulieS_Duq both tags seem to be firing correctly, in fact even console says they are duplicated.

Have you checked in Meta Business panel if their debugger shows any page views?

@jfidala Indeed, they do

However, Meta does not detected them

This is the error message from Meta Pixel Helper

And when I try to create a new event in Meta, it says the pixel isn’t on the website

Any idea what the issue could be ?

@JulieS_Duq Meta Pixel helper shows for me that it loaded tag fine. Are you using adblocker?
